GeneralQ We have a large project involving shotcreting soffits in an underground parking garage. The shotcreting overhead is not the problem; the problem is properly screeding the excess shotcrete from the ceiling leaving a semi-smooth finish.
Properly screeding and finishing overhead shotcrete is very challenging. The contractors who do this type of work properly have very well-trained and skilled tradesmen throughout the crew, including the nozzlemen, rodman, and finishers. Shotcrete that is not screeded and finished properly will likely suffer bonding and other issues.
